Dragon's Pupils - The Sword Guest (Dragon's Pupils Series Book 1‪)‬

When East and West combine…

Half-Chinese, half-Australian, Liz is not interested in her father’s ancient Tao wisdom, or his cryptic tales. She is more concerned with environmental issues—particularly the plan to mine one of Australia’s great landmarks, Wave Rock. Her father’s latest gift, a Chinese calligraphy pen, seems set to take its place in her bottom drawer forever.
Then Wave Rock is blasted open by something more than a mining operation, and Liz finds that she must battle monsters from ancient times as well as creatures from other worlds, all intent on destroying Earth. She must call on all her powers, from both her Eastern heritage and her Western upbringing, to save her world. Her pen becomes her way into a new and magical world, and Liz discovers she has powers—and allies—that she never could have guessed.
An exciting, fast-paced tale that combines the wisdom of ancient tradition with the pace of a Kung Fu movie and brings them to life in contemporary Australia, this exciting tale takes the best of two cultures and blends them to open up a new world of adventure and mystery.
